DOUBLE-CYLINDER SUCTION AND FORCE PUMP.

Specicaton of Letters Patent No. 625, dated March 10, 1888.

To all whom it may concern Be it known that I, JAMES J. RICE, of thetown of Salina, in the county of Onondaga and State of New York, haveinvented a new and useful Improvement inthe Construction of Pumps forRaising Water, called Rices Double-Cylinder Suction and Force Pump,7which is described as follows, reference being had to the annexeddrawings of the same, making partof this specification.

This pump has two cylinders of different; diameters one placed withinthe other leaving a space between them in which the valves;

work and through whichthe water rises-the inner one being closed at topand bottom, the outer one being open. y

The inner cylinder of the pumpwhich is marked A Figure 1 in the annexeddrawing, is constructed of any convenient length and dian eter,according to the situation in which it is to be used, and has a rim B,around it at the bottom of the same diameter as the inside of the outercylinder; said rim being perforated with two apertures C, C, Fig. 5 forthe admission of the water from the well or other place from whence itis to be raised into the pump, each aperture being the segment of acircle of lesser diameter than the rim, one being made in the rim on oneside of the cylinder and the other on the opposite side and both coveredby hinged valves D', Dd, Fig. l of a corresponding shape to saidapertures which they alternately open and shut; the valves open upwardin the space between the inner and outward cylinders and shut down uponthe rim which answers as the seat of said valves when the pump standsvertically.

Near the upper ends of the cylinder and surrounding the same is anothercircular rim E similar to that just described and perforated in likemanner with two apertures F, F Fig. 6 also the segment of a circle oneof which F is covered with a hinged valve G Fig. l opening upward andthat is placed perpendicularly over valve Dd, of the bottom rim, theother aperture F is left open. (The outer and inner cylinders arerepresented as being transparent in order to show the valves, pistons,&c.)

Between the two valves and in the center of the solid part of the rimsbetween the valves are placed two partitions H H Figs. l and 74extending from one rim to the otherww one on each side and filling thespace between the two cylinders and shutting off all v communicationfrom oneside to the other.

In one side of the inner cylinder above the bottom rim is an aperture IFigs. 1 and 8 communicating with the inside of said cylinder below thepiston. Under the top rim is a similar aperture, Figs. 1 andV 8coninunieating with the inside of thecylinder above the piston but onthe opposite side. Between the two before mentioned circular rims andnearer to the bottom one is a'rim K Figs. 1, 7, 9, extending around'halfofthe n cylinder from one partition to the other, pierced with a valveaperture L, similar to those above described and covered with avhingedvalve m, Fig. l of a similar descrip`r tion .opening upward.

The piston N, is of the ordinary construction and works tight inside theinner cylinder. The piston rod O works through the packing box P Figs. land 2. This packing boxconsists of a hollow tube Q open at one end andclosed at the other except the aperc ture for the piston rod. Said tubehas a male screw cut on its outer surface attheV the pressure of thewaterabove thecap forming a shoulder which rests upon the end of thecylinder.

The bore being made in the earth tothe depth required and strongly tubedthe before described pump is let down to the bottom the piston rodextending to the top and above the surface of the ground where it isworked in the usual manner by lever and hand or any mode or by any powerdesired. The outer cylinder may form part of the tubing of the bore andmay be placed in any desirable situation.

When it is required to place the pump at the surface of the ground aflange f Fig. 1 must be formed around the outer cylinder at the. bottomby which to bolt it down to a platform.

The operation of this pump is as follows: When the piston N is raised avacuum is produced in the cylinder below it, which is instantly filledby the water rising through the valve D. On thereturn of the piston thisvalve is closed and the water being thus prevented from returningthrough said valve is forced upward through the valve M and through theaperture F in the upper rim into the tube at the same time creating avacuum in the cylinder above the piston which is filled by the Waterrising through the opposite valve Dd on the lower rim B, which valve, asthe piston again rises is closed and the water above is forced upwardthrough the valve Gr in its upper rim into the tube. In this manner theoperation is continued until the water is forced to the surface of theground; or as high as the tubing may extend, where it flows off to anyplace desired. Y

When it is required to throw the Water to any height in a steady streamthe top of the outer cylinder must be closed by bolting a circular plateR Fig.4 to a circular flange S, projecting at right angles from thecylinder and making the joint tight by inserting packing between saidplate and Hange. Ihe packing box through which the piston rod passes is,in this case, to be constructed by extending a cup T Fig. 3 from theunder side of the circular plate into which the packing is put-thebottom of which cup being pierced with a round aperture for the pistonrod to pass through. A stopper U for forcing the packing around thepiston rod, flanged on the upper end and pierced with a round aperturefor the piston rod to pass through is inserted into a round aperture inthe top plate to which plate it is secured and forced down upon thepacking by nuts and screws V. The lower rim B of the inner cylindercloses the bottom of the outer cylinder except at the valve apertures.The outer cylinder Z being thus made perfectly tight so as to conne thewater is pierced with an aperture for a spout or neck W, to which a tubeor hose may be screwed.

The mode of operation is the same as that before described except thatinstead of the Water rising in a vertical tube and flowing o' in themanner first stated it is conned within the cylinder and forced througha tube in the manner of a fire engine to great elevations.

' In this pump the pulsation of the column of water arising from thesuction and pulsion of the piston is nearly destroyed, without the useof an air vessel or globe. The same arrangement of the working parts asthat above described may be used to advantage in the construction ofengines for the extinguishment of fires.

By the above novel construction of the pump it is not only renderedstronger and less costly, but from its neat and compact form can beintroduced into small bores of great depth below the surface of theground whereit forms the section of the continuous tube; or it may beplaced inside the tube at the bottom, or at pumpingdistance from thesurface of the water or in any situation desired Yand by its `use thetube is not liable to be broken as is the case in the use of the pumpWith a single valve at the bottom and a side tube with a valve throughwhich the water is forced upward.

The 'cylinder may be surrounded by a square or polygonal trunk of `vvoodof any suitable material with corresponding valves.

The invention claimed by me the said JAMES J. RICE and which I desire tosecure by Letters Patent consists in The before described constructionof the pump With the additional outer cylinder the partition in thespaces between the outer and inner cylinders and the form andarrangement of the valves inthe circular rims between said cylinders.
